Fanfaron

A swaggering bully; a cowardly boaster who blows his own
trumpet. Sir Walter Scott uses the word for finery, especially for the
gold chains worn by military men, common in Spain amongst the
conquerors of the New World. (Spanish, fanfarron, a bully;
French, fanfare, a flourish of trumpets, or short piece of
military music performed by brass instruments and kettledrums.)
